Mace to anakin= When the senate learns what has transpired here they will kill us.. Along with all the jedi.

Anakin= I agree the senate's next move will be aganist the temple.

Add to that :

Yoda : Destroy the Senate, we must.

Seriously, like I posted before, the Jedi have very very little tact. They couldnt possibly have suceeded with appeasing the Senators. They should have forseen this, but the dark shroud of arrogance clouded their abilities.
